Unit gets to the rinse cycle and just turns off because it will not drain water from the tub. Unhooked all the drain tubes and checked for blockages and there are none, it doesn't even sound like it is trying to come on. I unhooked both the drain pump and the circulation pump and cleaned out what little gunk was in there and it did the same thing,

Pulled out the multi meter and the drain pump is testing at 14.5 so it is within spec but even when i run it in the QC mode and go to test the drain pump it makes no noise, same when i try to test the circulation pump, nothing.

Could this still be just the drain pump going bad? Are there any other tests I can run on it, or anything else I should be looking for?

Just a follow up in case anyone experiences something similar, I played around with the drain pump a little more and was able to get it running in QC mode, started a rinse spin and dry mode and it was draining but stopped part way through the cycle again and displayed an OE error.

I went in and swapped out the drain pump and the old one was super hot. I don't know if it's normal or not but it was really hot to the touch for almost an hour after pulling it out.

Ran same cycle with the new drain pump and it went all the way through, problem solved. Once the old drain pump had finally cooled down I inspected it a little more and was trying to get some more of the lint away from the rubber gasket and realized that you can you can pull the pump apart into two sections and the inside was full of lint, haven't tested it after removing all the lint but I wish I would have checked that before buying the new one.

If your linen filter is clean and drain pump sound like it is running there there may be a linen buildup inside of the pump. You may need to remove the pump and disassemble it. The pump rotor is separated from the stator with a plastic compartment. Inside mine was a LOT of gunk that made pump less efficient, so water was not completely drained
